77c84f2def #12098: Make multiprocessing's child processes inherit sys.flags on Windows

59d5404bc7 Issue #14753: Make multiprocessing treat negative timeouts as it did in 3.2 
In Python 3.2 and earlier, Process.join() and Connection.poll()
treated negative timeouts as zero timeouts.  Earlier versions from
the 3.3 line of development treat them as infinite timeouts.

The patch reverts to the old behaviour.

  Fix #9513 to remove relative imports from multiprocessing.

  The test suite currently skips test_multiprocessing on Windows
  because it fails on finding _multiprocessing in several
  win32-specific blocks. Removing the relative import lets this
  through and allows the test to run (and pass).
